If you love the look of Aritzia’s cozy, oversized sweat sets but don’t love the price tag, Costco may have yet another budget-friendly alternative worth checking out. The warehouse retailer is once again getting attention for Tuff Athletics sweats that shoppers say give off major Aritzia vibes—and this time, TikTok is taking notice of the full-zip version.

In a TikTok from @vancitycostcodeals, the creator showed off the Tuff Athletics full-zip sweatshirt and matching sweats, asking, “Does Costco have another Aritzia dupe?” Both pieces were on sale for just $19.99, making the full set less than the price of many single Aritzia pieces.

Costco Shoppers Are Loving This Aritzia Dupe

The Tuff Athletics Women’s Oversized Fleece Hooded Full Zip has the kind of oversized, minimalist silhouette that Aritzia’s popular Sweatfleece collection is known for. It features dropped shoulders, ribbed cuffs and hem, an adjustable hood and an ultra-soft brushed interior. The sweatshirt is also made with 78% cotton and 22% polyester.

And Costco shoppers have been fans of Tuff Athletics for years. In a Reddit thread about Costco workout clothes, shoppers called the brand’s pieces “every bit as good and soft” as more expensive workout clothes, with one person saying they regularly buy multiple pairs when they’re in stock. Another Reddit user described Tuff Athletics as a Costco brand with “incredibly good quality” and said the prices were hard to beat compared with premium activewear.

TikTok creator @alana_mk is also getting in on the trend, showing off the Costco sweat set and captioning the video, “Run don’t walk.” One commenter summed up the reaction with a simple, “Ooo love.”

With the sweatshirt and matching sweats both spotted for $19.99, it’s easy to see why shoppers are running to Costco for the set. If you’re after the cozy Aritzia look without the Aritzia price, this one might be worth adding to your next Costco trip.
